2 step colder spark plugs ??
I'm going to be ordering NGK 2 step colder copper plugs and wires and am wondering what the part # for this is? I know you just change the last 2 numbers ... but what is our part number for the stock ones?

Unless you're actually circle-track racing the car, there is such a thing as too cold a plug. And as an FYI, proper NGK "race" plugs are about $30 each.
A little searching did turn up one cross-reference that has the right dimensions- the IFR8H-11 (stock #5068). It's an irridium "street" plug, 14mm x 19mm, 5/8" hex, gasket seat, resistor, etc. They're listed at a mere $12 each.
Let us know how they work out. I'm curious about this one myself.

Spark plugs are spark plugs. No such thing as "Honda plugs" vs "Mazda plugs" per se.
There's a only few basic combinations of thread diameter, thread length, hex size, seat type, etc. So any one particular plug is gonna fit dozens of different vehicles.
It's like saying I run "Honda wheels". No, I run 15x7 wheels with a 4 bolt 100mm pattern and +41 offset. That they happen to also fit just about every vehicle Honda has ever made (as well as a bunch of Toyotas, Nissans, etc) isn't terribly important.
My bad, I forgot we started allowing their kind on this board. (just kidding, everyone)
Actually, isn't the 5E also standard on auto 1.6s? Not sure I understand that one fully...
I think as an experiment I may buy one of the IFR8s and stick it in my engine for a while- see how it compares to the BKR7Es after a few hundred miles. Some side-by-side photos may help illustrate this for folks.

BKR6E-11 is standard for 1.6, but Braineack is right- the 5 is spec'd for 1.8s. And I was wrong about the 1.6 Autos- they got the same heat range but the FSM lists a Nippondenso plug for them as opposed to NGK. Damn odd.
